Installation of Babl

First, fix a typo that causes Meson to fail to run: 

sed -i '/check:/d' meson.build

Install Babl by running the following commands: 

mkdir bld &&
cd    bld &&

meson --prefix=/usr --buildtype=release .. &&
ninja

To test the results, issue: ninja test.

Now, as the root user: 

ninja install &&

install -v -m755 -d                         /usr/share/gtk-doc/html/babl/graphics &&
install -v -m644 docs/*.{css,html}          /usr/share/gtk-doc/html/babl          &&
install -v -m644 docs/graphics/*.{html,svg} /usr/share/gtk-doc/html/babl/graphics

Command Explanations

install -v -m755 -d /usr/share/gtk-doc/html/babl/graphics: This and the subsequent commands install the library html documentation under /usr/share/gtk-doc/html where other gtk packages put the programmer-oriented documentation.
